      3 # Tests for the special source .PRECIOUS in dependency declarations, which
      4 # is only relevant if the commands for the target fail or are interrupted.
      5 # In such a case, the target file is usually removed, to avoid having
      6 # half-finished files with a timestamp suggesting the file were up-to-date.
      7 #
      8 # For targets marked with .PRECIOUS, the target file is not removed.
      9 # The author of the makefile is then responsible for avoiding the above
     10 # situation, in which the target would be wrongly considered up-to-date,
     11 # just because its timestamp says so.
